ANATOMY

Detailed explanation-1: -Your musculoskeletal system includes your bones, cartilage, ligaments, tendons and connective tissues. Your skeleton provides a framework for your muscles and other soft tissues. Together, they support your body’s weight, maintain your posture and help you move.

Detailed explanation-2: -Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. Then, when the movement is completed, the flexor relaxes and the extensor contracts to extend or straighten the limb at the same joint.

Detailed explanation-3: -The muscular system works in conjunction with the skeleton to produce movement of the limbs and body. Ligaments and tendons are two main types of connective tissues that help the muscular-skeletal system produce movements.

Detailed explanation-4: -The skeletal system helps maintain mineral homeostasis by regulating the level of calcium and other minerals in the blood by storing or releasing them from bones as needed. This process also helps maintain homeostasis in blood pH because the minerals are basic.

Detailed explanation-5: -Also, the skeletal muscles have a striated look from the sarcomeres, or units that are responsible for helping the cells contract and relax together. The structure of the skeletal muscle helps it perform its function because the sarcomeres helps the cells work together and contract or relax at the same time.
